In this and his later book "Continental Drifter", Tim Moore takes an old travelogue and broadly re-traces the journey. The original in this case is a Victorian account of a journey to Iceland, Norway and Spitzbergen (Letter from High Latitudes by Lord Dufferin - well worth a read too).
If you've ever enjoyed a Bill Bryson book you'll love this. He's clever without being a smartarse, funny without losing the book's focus, and researches his subject with real thoroughness, while still eagerly seizing on all cheap laughs wherever they can be found. What's more, unlike any of Bryson's books, he has a well-defined aim which he (mostly) sees right through to the end.
The descriptions of his destinations are wonderfully well-observed, helped by the huge changes of recent history. His reflections on Lord Dufferin himself are colourful and poignant. And the joke from which the title originates is a cracker.
